Rainbow Dash has been friends with Pinkie Pie for years. Best friends, actually. She knows her very well, and they've been together through a lot of hardships that only made their friendship strong —though kinda rocky in the beginning.
So, if she knows her so well, why suddenly she wonders where Pinkie's talent to make ponies happy comes from?
Dedicated to one of my dearest, most understanding friends, whose mails never fail to make me smile: TheMareWhoSaysNi. Thank you a lot for standing me and my silly rants
